I copied the code for the 4120C and tried several values around 2 mm and
2.5 mm (in 600dpi units) with no change. Do you think there is a slim
chance that the values need to exactly match what the scanner expects
(the missing vpd-values) to activate overscan, and otherwise they are
just ignored? How were the values for the 4120C established?

Best regards,
